I'm sorry to spread the bad news people, but the marks you got back for the Edexcel Maths modules are NOT an indication of your final percentage mark. The marks you were given back out of 100 are ONLY UMS marks. UMS is a type of mark that relates to a fixed curve, and its main purpose is to ensure that all the different papers every year are marked onto a fair based scale - for example, if one year a maths paper is blantently more difficult than the previous year, then it will be marked down to match it via UMS.

If you for example had 90/100 UMS, it does NOT mean your final result percentage is 90%, your final percentage score can fluctuate above or below 90. It is not very good news, but on the bright side, if you had a high UMS mark it does indicate your percentage is quite high anyway, and if you had a low UMS mark it means there is a chance it might be higher. Your UMS mark does not differ from your real mark that much, and I think it fluctuates about 10%-15% or 10-15 marks.

There has been a discussion about the Edexcel maths module marks that were received a few days ago (when the real marks are suppose to be out next Thursday), and at the moment the results or marks received by the teachers via Edexcel are ONLY UMS marks and NOT an indication of your FINAL percentage score which will be correctly published next Thursday.

For more information get your school to contact Edexcel. By the way, this only applies to the Maths results for all I know, other subjects I am not sure about.

The only thing that EVER comes out on results slips for A-Level stuff are UMS scores, and thats for every exam board.

The important thing is knowing how the paper was weighted (ie max UMS available) and the relevant scale, all such scales are normally listed on the back of the results slips with the accompanying notes.
